Windows 7 – How to Make Mouse Wheel Button Perform a Double-Click

Answering myself since this is what fixed it in the end. So in the end buying a new logitech mouse and installing its drivers seems to have fixed the issue. At least for now. Thanks for everyone who tried to help.

Autohotkey is a light solution, with the script:

*MButton::SendInput {Click 2}

You can even compile it to an executable, which weighs about 200KB in disk space and 2.2MB¹ in memory. It's also quite easy to add to startup, and is portable.

I personally prefer to use X-Mouse Button Control due to ease of configuration. Simply assign the Middle Button to Double Click Drag. The advantage is it keeps the second click held as long as the middle button is held, which ensures greater compatibility - it should perform exactly the same way as double clicking normally.

^{Click for full size}

It's possible to simulate such an action in AHK, but more difficult - if you wish for such an AHK solution, you can let me know in a comment. The above AHK script will not respond correctly to holding the button down - it will simply double click and release.

X-Mouse Button Control weighs about 3MB in disk space and 3MB¹ in memory. It is also optionally portable.

Both AHK and XMBC can accomplish this, and both can be set to have application specific profiles. XMBC is more intuitive, if you wish to modify other mouse buttons without having to learn a scripting language, while AHK is undoubtedly more powerful. ^{Both AHK and XMBC can simulate chains of keypresses, but AHK allows for more complex operations and decision making.}

As an aside, AHK will trip PunkBuster (a certain anti-cheating system used by quite a few games), while XMBC will not - at least, at the moment.

¹The memory usage is on my computer, Windows 7 x64. It may vary slightly from computer to computer, but the variation shouldn't be much.
